Do you have any codes?

I had two codes PO422 for front bank oxygen sensor and PO507 for Idle air control module. Bought both items and installed them and removed codes. Codes stayed off. Ran good for two days and then the same problem came back with the engine cutting off for a split second, the tach dips for same time and now the check engine blinks at the same time. Only does it for a few seconds at a time not all the time.

The check engine light is not on so I have not had them checked today. The check engine light only blinks at the same time as when it misses and the tach drops. Will there be any codes when the check engine light is off. If so I will have it checked tomorrow.

RAined last night and it is cold. Car starting cutting off and on instantly and did it often. Check engine light blinking off and on and tach dropping at the same time. I had the codes checked afterwards and there are no codes.

If the check engine light is flashing while its running then there is going to be codes.
